[Diagnostic and therapeutic problems in SARA syndrome (sexually acquired reactive arthritis) particularly considering the role of Chlamydia trachomatis].

Reactive arthritis triggered by a sexually transmitted infection is referred to as sexually acquired reactive arthritis (SARA). There is no gold standard for the diagnosis of SARA. None of the tests or the clinical symptoms alone are strong enough to make a definite diagnosis of SARA. Tests to identify Chlamydia trachomatis, when respect typical clinical symptoms are helpful to make the diagnosis of ReA.
